Specilcation of Letters Patent. Patented June 28, 1910,

Application tiled August 26, 1909. Serial No. 514,666.

To all whom 'it 'may concern.:

Be it known that I, WLLLIAM L. Dr. Renan, -a citizen of the UnitedStates, residing at Chica-go, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inTie-Plates, of which the following is u specification.

My invent-ion relates to tie-plates and the object thereof is to providea tie-plate having many advantages not only in the matter of manufacturebut also in the mat-ter of ef ficieney and reliability in actual use.

Speaking in general terms, my tie-plate comprises a. body portion orplate proper on which the rail rests and a plurality of removable andadjustable portions or blocks which bear against. the opposite sides ofthe rail flange and are secured to the plate proper by the spikes whichhold the rail and tie-plate to the tie. This construction of tie-plateis simple and economical of manufact-ure and has the advantage of beingadapted for use in connection with rails of different size as to flange,the only change necessary for the proper adaptation heilig the locationof the spike holes in the plate proper and in the adjustable portions orblocks.

In the drawing Figure 1 is a partsection and part elevation of my newforni of tieplate with the rail in section, said tie-plate and railbeing shown secured to a tie; Fig. 2 a plan view of the tie-plate propershowing at one end a series of the removable and adjustable blocks, theblocks at the opposite end being removed to show the position of thespike holes; Fig. 3 a. plan view of a portion of such tie-plate propershowing spike holes therein adapting the plate for diii'ercnt sizes ofrail; Flg. l a sectional elevation on the line of Fig. 1; Fig. 5 aperspective of one of the adjustable blocks; Fig. 6 a view somewhatsimilar to Fig. l but Wholly in section and illustrating'a moditied formof tie-plate; Fig. i' a perspective of one of the removable portions orblocks shown in Fig. G; and Figs. 8 and 9 sections showing othermodifications.

Referring to the embodiment of my invention as shown in Figs. 1 to 5, mytic-plate comprises a body portion or tie-plate proper marked 1 and aplurality of removable and adjustable blocks 2 which here haveinterlockin engagement both with the rail and with t e body portion ofthe tie-plate. To this end said body portion is provided with one ormore longitudinal grooves 1 which by preference as herein shown arethree in number. rithin these grooves titthe depending port-ions 2 ofthe blocks 2 with the result that said blocks are movable within saidgrooves longitudinally of the plate and transversely of the line of railA.

It will be understood that any desired number of grooves and blocks maybe employed and that, even while l have drown three grooves only two ofthe saine need be utilized for the blocks. l have accordinglyillustrated in full lines in Fig. 2 two of the adjustable blocks at oneend of the plate orcupying the two outermost grooves, and a third blockin dotted lines occupying the middle groove. I have illustrated bydotted lines with respect to the outermost blocks the feature-of theadjustability of the blocks longitudinally of the grooves in order toaccommodate rails of different flange widths.

On the other end of the plate l there may be employed a single block inany one of the grooves, or tivo blocks in any tivo thereof, or a blockin each one of such grooves. Each of the blocks 2 is provided on Vitsupper side with a fiat portion 2" through which the spike hole 2 passesand with an inclined portion Q against which the inclined underside ofthe head of the spike 3 which is here a screw spike, bears. It will beunderstood that the plate is pro vided with spike holes 1h which arelocated aeeordin to the particular width of rail flange with which .itis to cotiperate, the spike holes in the blocks being of course alwaysthe same inasmuch as these. blocks are adjustable along thegrooves inorder that their spike holes may register with the correu sponding spikeholes in the plate proper. By preference though not of neoessity, thetie plate proper may be provided on its underside with a series offlanges l which engage the top surface of the tie 4 and which here arelongitudinal of the plate.

As a convenient way for adapting the saine plate to different sizes ofrail, such plate may be provided with a series of pairs of spike holes1E as shown in Fig. 3 to accommodate two diferent standard sizes ofrail, and it is obvious that slot-s may be substituted for such pairs ofholes.

lVhen the parts of the tie-plate and the rail are in place as shown inFi". 1 the s ikes as well as the rail itself liold the b ocks inposition, the flanged portion 2 of such blocks extending partially underthe rail flange and there interlocking there with and the shoulder J ofeach block form ing tho abutment for a .side of the rail flange as shownin Fig. 1. l

In Figs. (i and i' I have illustrated a modified form of construction oftic-plate in which the body portion or tie-plate proper marked 5 isperfectly flat as to its upper face, that is ungroovcd, and providedwith the adjustable and removable portionsor strips 6 resting {lat ucponsaid body portion and having an exten inwardi directed underneath therail flange as clear y shown in F ig. 6. Each strip 6 is provided on itsupper face with a {iat portion t3 having spi te holes 6, in the forni ofslots, and inclined surface (la, agaii'xst which the inclined undersideof the head of the screw spike 'T bears andra shoulder ti against whichaside of the ra1l flange abuis. However, this adjustable strip or blockdif- Jters from the first described forni in that it extendstransversely and all the way across the plate it is obvious that theseremovable blocks or strips (3 are adjustable to tit properly upon theplate 5 in order to adapt it to the particular rail to which thetie-plate is applied, it being understood that the plate 5 is likewiseprovided with elongated or slot-like spike holes 5 for said adjustmentpurposes. This forni of tic-plate` extremely simple and economical ofmanu facture and the saine is readily adapted for diiterent rail flangewidths. the only change necessitated for diilerent rails being thelocation of the spike holes in the plate 5.

to slide upon each other there-at for adjustment purposes. Theseportions may or may notbe provided with a so-called abrasion plate butin the present instance I have shown such a plate 9.

As shown in the modification illustrated nient obtained by d iiierentpositioning with respect to complementary projections andi notches orgrooves in the plate and blocks. To this end the blocks l() have ontheir under i surfaceaseries of projections and notches which tit'corresponding projections and notches in the plate 11E which bypreference ed iianged portion 6a having a longitudine in Fig. 9,A the adjustablc blocks may be iutcrlocked with the plate proper and the adjustirests upon a bottom plate 12. It will be understood that theseprojections and notches have a certain relation to the standard railflange widths so that when the parts of the tie-plate are in therelative position shown they will accommodate a certain iiange width andthat. when the blocks are adjusted outwardly the distance of one notchthey will accommodate another flange width. This tie-plate like theothers may be pro vided with either transverse or longitudinal bottomflanges but in the present instance these anges 12a which are on thebottom plate are of the longitudinal type.

I claim:

1. .t tie-plate comprising a body portion, and a portion adjustablethereon in a longitudinal line toward and away from the rail when inposition, said adjustable portion having a spike hole; substantially asdescribed.

2. A tic-plate comprising a body portion, and portions adjustablethereon longitw dinally toward and away from the rail when in position,said adjustable portions being arranged to interlock with the bodyportion; substantially described.

3. A tie-plate comprising a body portion, and portions adjustablethereon longitudinally toward and away from the rail when in position,said adjustable portions being arranged to interlock with both the bodyportion and with the rail; substantially as described.

-ls .i tie-plate comprising a body portion having a longitudinal groove,and blocks i'iti ting and movable therein toward and away In Fig. S Ihave illustrated another modi l'ication wherein the adjustable portionsare l reduced at their adjacent ends and arranged from the rail when inposition, and having spike openings; substantially as described.

A. tie- )late comprising a body portion having a p uralit-y oflongitudinal grooves, and a plurality of blocks fitting therein atopposite ends and having spike openings; substantially as described.

G. A tie-plate com )rising a body portion l groove, and blocks fitF tingand movable therein toward and away from the rail when in position. andhaving spike awnings` said blocks having inwardly directed flangesextending beneath the rail 105 when in position; substantially asdescribed.
